Problems solved by technology

The controllability of the production process of this method is not strong, and the shape of the prepared copper sulfide particles is not very regular.
In addition, there are currently chemical deposition methods, sonochemical methods, and template methods. These synthesis methods generally require higher reaction temperatures, reaction pressures, longer reaction times, and specific reaction devices. These conditions limit the use of nano-copper sulfide. Application in actual production, so it is very important to find a method for preparing copper sulfide nanomaterials that is easy to operate, mild in reaction conditions, and low in cost.
